Detailed Description
template<class TInputImage, class TOutputImage, class TKernel>
class itk::MorphologyImageFilter< TInputImage, TOutputImage, TKernel >
Base class for the morphological operations such as erosion and dialation.
This class provides the infrastructure to support most morphological operations. Subclasses of MorphologyImageFilter implement specific "binary" and "grayscale" operations. The "binary" subclasses can operate on gray level data, where a specified a pixel value is consider the "foreground" and every other pixel value is considered the background. This is useful for operating on segment masks where all pixels assigned to segment #1 have value 1, all pixels assigned to segment #2 have value 2, etc. Here, a given segment can be dilated (expanded) while treating all other segment identifiers are background.
The "kernel" specified represents a morphology structuring element. The structuring element is a small Neighborhood with values indicating an element is "on" (value > 0) or "off" (value <=0). Morphological operations are defined by placing the structuring element over a pixel, and calculating a nonlinear function (min, max) over the pixels of the image that are under pixels in the structuring element that are "on". The result of this calculation is the value of the pixel in the output image. Under most circumstances, the "center pixel" of the structuring element -- or structuring element pixel over the input pixel under consideration -- is prescribed to be "on". This is not a strict requirement but the subclasses of this filter are not guarenteed to produce the correct result if the "center pixel" is not part of the structuring element.
Subclasses of this class can define their own operations by simply providing their own Evaluate() protected member function.

MorphologyImageFilters need to make sure they request enough of an input image to account for the structuring element size. The input requested region is expanded by the radius of the structuring element. If the request extends past the LargestPossibleRegion for the input, the request is cropped by the LargestPossibleRegion.
